Before we had an "imagepack server" for ECC, where you can download complete packs...but this is gone atm, due to bandwith reasons!

To insert only specific images with ECC Imageinject though icc server is not supported, however...you can import images with the EMUMOVIES option.
Or....download all with ECC Imageinject (ICC) and export the imagepack, in there you can put the images you want back in the ECC folders.

I download everything then i open the specific folder through ECC, search for "cover", "media storage", e.t.c and delete accordingly. So no problem. I was just asking in case i missed a (hidden?) option to download specific image types.
